KahBang, a two-day music, film, and arts festival being held on the Bangor Waterfront on August 10 and 11, revealed its lineup of nationally known headliners and local Maine acts. Rapper Wale, electronic musician Bassnectar, and alternative rockers the Deftones will be the main attractions at the festival. The festival, now in its fourth year, will also feature several local Maine musicians such as Milkman's Union, Spose, the Mallet Brothers Band, and more. Last year KahBang brought around 8,000 people to Bangor for its weekend of music, art, and film.
